How do I check allowance charges against the original allowance schedule with AI before I write the adjustment?
Contract allowances for owner selections sit on a schedule in the agreement, then charges show up as vendor invoices, tickets and quotes that are often coded inconsistently or not coded at all. The silent failures are charges with no matching allowance, descriptions that do not match the allowance scope, labor billed against a material-only allowance, a remaining balance that goes negative, pending adjustments treated as if they were already approved, duplicate invoice numbers, and allowances that still have no charges. Have Claude or ChatGPT read the charge documents into one table and propose matches to the allowance schedule, and have Copilot in Excel or Gemini in Google Sheets flag every mismatch and compute remaining balances using only approved adjustments before anyone writes the allowance adjustment. Whether an overage is an owner change, a contractor cost or a coding error stays with the project manager under the contract.

Short answer
Use Claude or ChatGPT, then Copilot in Excel or Gemini in Google Sheets: Claude or ChatGPT reads allowance charge documents into one Charges table and proposes matches to the contract allowance schedule; Copilot or Gemini sums charges by allowance, computes remaining using only approved adjustments, and flags unmatched or blank IDs, description mismatches, labor on material-only allowances, negative remaining, pending adjustments treated as approved, duplicate document numbers and unused allowances. Contract allowances for owner selections sit on a schedule in the agreement, then charges show up as vendor invoices, tickets and quotes that are often coded inconsistently or not coded at all. The silent failures are charges with no matching allowance, descriptions that do not match the allowance scope, labor billed against a material-only allowance, a remaining balance that goes negative, pending adjustments treated as if they were already approved, duplicate invoice numbers, and allowances that still have no charges. Have Claude or ChatGPT read the charge documents into one table and propose matches to the allowance schedule, and have Copilot in Excel or Gemini in Google Sheets flag every mismatch and compute remaining balances using only approved adjustments before anyone writes the allowance adjustment. Whether an overage is an owner change, a contractor cost or a coding error stays with the project manager under the contract. A person still checks: every flag against the invoices and the contract allowance schedule before anyone writes an adjustment; entitlement and the adjustment amount stay with the project manager under the contract.

Tool: Claude or ChatGPT, then Copilot in Excel or Gemini in Google Sheets
Claude or ChatGPT reads allowance charge documents into one Charges table and proposes matches to the contract allowance schedule; Copilot or Gemini sums charges by allowance, computes remaining using only approved adjustments, and flags unmatched or blank IDs, description mismatches, labor on material-only allowances, negative remaining, pending adjustments treated as approved, duplicate document numbers and unused allowances.
Prompt 1
Read these allowance charge documents [upload invoices, tickets or quotes]. Build a Charges table with one row per charge: date, vendor, document number, description, amount, allowance ID as written, document type. Copy values exactly and write NOT SHOWN or BLANK instead of guessing. Then propose a match to this allowance schedule [paste: allowance ID, description, original amount, material-only or includes install, approved adjustments] with a confidence word (clear, likely, unsure). Do not invent an allowance or decide an adjustment.
Prompt 2
EXAMPLE DATA ONLY. Here are my Allowances, Pending and Charges tabs [paste the example rows]. Write Excel formulas (or a step-by-step Copilot plan) that match each charge to an allowance, sum charges to date, compute remaining as original plus approved adjustments minus charges (ignore pending adjustments), and flag: no matching allowance, blank allowance ID, description mismatch, labor billed against a material-only allowance, remaining below zero, a pending adjustment treated as approved, duplicate document numbers, and allowances with no charges yet. Use only my data; do not decide an adjustment amount or who pays.
Human check: Every flag against the invoices and the contract allowance schedule before anyone writes an adjustment; entitlement and the adjustment amount stay with the project manager under the contract.
The problem
Check allowance charges against the original allowance schedule with AI. This is a common, time-consuming task for a project manager.
What this workflow does
Contract allowances for owner selections sit on a schedule in the agreement, then charges show up as vendor invoices, tickets and quotes that are often coded inconsistently or not coded at all.

How it works: AI drafts or analyzes. A person operates the tools, checks the work, and takes action.
Your checkpoint: The workbook only compares the charges you entered with the allowance schedule you entered. An overage can be a valid owner selection, a coding error or a scope question, so a flag is a question for the PM, not an adjustment. Who pays, and the adjustment amount, stay with the project manager under the contract.
Before you start
- Access to the named tool; confirm license, version and cost with the vendor.
- A small, non-confidential sample to try the workflow on first.
- A qualified person to review the output before it is used.
Tools and access
Follow the steps
- Export or type the contract allowance schedule as an Allowances tab: allowance ID, description, original amount, whether the allowance is material-only or includes install/labor, and approved adjustments only (amount and reference). Keep pending or rejected adjustments on a separate Pending tab so they cannot inflate remaining.
- Collect charges coded (or that should be coded) to allowances: vendor invoices, tickets, owner-selection quotes. Use an AI account your company allows for cost data.
- Have Claude or ChatGPT read every charge into a Charges tab: date, vendor, document number, description, amount, allowance ID as written, and document type. It copies values exactly and writes NOT SHOWN or BLANK instead of guessing.
- Have it propose a match from each charge to an Allowances row with a confidence word (clear, likely, unsure). You fix the unsure ones. Do not let it invent an allowance or an adjustment amount.
- Have Copilot in Excel or Gemini in Google Sheets sum charges by allowance, compute remaining = original + approved adjustments minus charges to date, and flag: no matching allowance, blank allowance ID, description that does not match the allowance scope, labor or install billed against a material-only allowance, remaining below zero, a pending adjustment treated as approved, duplicate document numbers, and allowances with no charges yet (informational).
- Review every flag against the invoices and the contract schedule. Write any allowance adjustment yourself under the contract; keep the flagged workbook with the billing backup.

Expected output

The Pending tab +1800 is not approved, so do not add it.

Do not add Pending amounts into Remaining. - Flag NO MATCHING ALLOWANCE when the ID is non-blank and XLOOKUP/VLOOKUP returns no Allowances row. - Flag BLANK ID when allowance ID as written is blank / NOT SHOWN. - Flag DESCRIPTION MISMATCH when the charge description does not share the allowance's scope words (you confirm). - Flag LABOR ON MATERIAL-ONLY when Includes = material only and the charge description indicates labor or install. - Flag OVER REMAINING when Remaining < 0. - Flag PENDING TREATED AS APPROVED when a Pending amount was added into Remaining. - Flag DUPLICATE when COUNTIF(document number) > 1 and you have not marked the rows as separate lines of one document. - Flag NO CHARGES YET when an Allowances row has SUMIF = 0, or has only mismatched charges (informational). Do not invent an adjustment amount or decide who pays — only flag for human review.

- Missing information is marked as missing, not filled in.
Limits and recovery
- The workbook only compares the charges you entered with the allowance schedule you entered. An overage can be a valid owner selection, a coding error or a scope question, so a flag is a question for the PM, not an adjustment. Who pays, and the adjustment amount, stay with the project manager under the contract.
- Check your organization’s data policy before sharing project files with third-party tools.
